Definitions

  • the present invention relates to an anti-inflammatory composition, an anti-allergic composition and a composition for improving atopic dermatitis using a Sargassum horneri extract or Ecklonia cava extract.
  • Atopic dermatitis is a recurrent chronic skin disease that occurs frequently in infancy, but it may persist in adults or develop into an adult, and its prevalence is increasing recently (Kor J Pharmacogn., 43: 59-65, 2012 ).
  • Atopic dermatitis is a type of allergic disease characterized by symptoms such as dry skin, itching, irritation, pruritus, swelling around the hair follicle, hypophytosis, ecchymosis, and eczema lesions (Korean J Invest Dermatol., 14: 67-72 , 2007).
  • the immune system a defense mechanism against external invasion of the human body, is centered on the activation of T cells.
  • the cytokines IL-2, IFN- ⁇ and TNF produced by Th1 cells induce the differentiation of Th1 cells and suppress the proliferation and differentiation of Th2 cells
  • IL-4, IL-5, IL Cytokines such as IL-6, IL-10, IL-13 and TSLP (thymic stromal lymphopoietin) induce the proliferation and differentiation of Th2 cells and inhibit the differentiation of Th1 cells (J Am Acad Dermatol., 44, S1- 2001). Under normal conditions, the interaction between Th1 and Th2 cells is balanced by maintaining the immune response.
  • Atopic dermatitis promotes the conversion of T cells into Th2 cells, and increased Th2 cells secrete a large amount of cytokines to produce IgE (J Clin Invest. 113 (5): 651-7, 2004; J Allergy Clin Immunol. 2003; 112 (2)), which induces hypersensitive responses by inducing mast cell and eosinophil differentiation : 252-62; Kor J Pharmacogn, 43: 59-65, 2012).
  • TSLP is overexpressed in skin lesions in patients with atopic dermatitis and overexpression of TSLP by keratinocyte in mice has been reported to cause atopic dermatitis (Nature immunology. 2002; 3 (7): 673-80 ; Methods in enzymology. 2014; 535: 371-87; The Journal of experimental medicine. 2005; 202 (4): 541-9).
  • Chemokine is a low-molecular protein that displays chemoattractants and is divided into four types according to its structure and function: C, CC, CXC, and CX3C. Recently, these chemokines have been implicated in the development and maturation of immune cells, And migration, Th1 / Th2 balance, and so on.
  • TARC Thimus & activation-regulated chemokine
  • CCR4 CC chemokine receptor 4
  • atopic dermatitis presents symptoms such as folliculitis, scurvy and dryness.
  • a feeling of pruritus occurs throughout the acute phase and the chronic phase, which is important in the treatment of atopic dermatitis because it causes secondary skin symptoms such as wound infection and secondary infection due to scratching.
  • the skin stimulation model tends to be preferred.
  • the skin irritation model is a method of inducing atopic dermatitis using chemical (DNCB: dinitrofluorobenzene, DNFB: dinitrofluorobenzene, PiCl: picryl chloride), which can induce dermatitis in a relatively short period of time with acute atopy induction model, It is useful for research because it has the merit of being able to visually confirm the wind and wind blasts.

Twenty-four hours later, the supernatant was removed, and triazol reagent was added to the cells. After adding chloroform, the cells were vortexed for 10 seconds and centrifuged at 12,000 rpm for 15 minutes. The supernatant was removed and mixed with isopropanol.

  • BMCMC cells were cultured for 2 hours at various concentrations and sensitized with anti-DNP-IgE (1 ⁇ g / ml) for 4 hours. Cells were washed with tyrode buffer and stimulated with DNP-BSA (100 ng / ml) for 30 min at 37 ° C. After 30 minutes, the supernatant was removed, and lysis buffer was added to the cells. The vortexing was carried out for 6 times for 10 minutes. The supernatant was centrifuged at 14,000 rpm for 10 minutes at 4 ° C and proteins were quantified using BCA kit.

  • 1% DNCB (Dinitrochlorobenzene) was applied to Nc / Nga mice deprived of the back region to induce atopic dermatitis first.
  • 1% DNCB and AD ointment 100 mg were applied to the depilated area, Induced atopic dermatitis.
  • oral administration was performed daily for 2 weeks and clinical analysis and scratching analysis were performed weekly.
  • the animals were sacrificed and the ear thickness, transepidermal water loss (TEWL), water and pH were measured and the blood, spleen, and lymph nodes were separated and analyzed.
  • TEWL transepidermal water loss
  • ear thickness of each individual was measured at 4th week. After animals were anesthetized, the right ear and left ear were divided into three parts, respectively, and caliper was used to measure the thickness.
  • Transepidermal water loss Loss of water through the skin is caused by evaporation of skin moisture and perspiration. Among these, transdermal water loss is caused by passive diffusion of moisture from the inside of the body to the skin, It is called water loss. To evaluate skin dryness, which is a typical clinical symptom of atopic dermatitis, transdermal water loss was measured at the 4th week of the animal experiment. After the animals were anesthetized, the atrophy-induced back area was measured for 30 seconds using a transcutaneous water loss measuring device (AquaFlux, Biox).
  • Moisture was measured at 4th week after the end of the animal experiment.
  • Skin-o-mat Cosmetic Medical Beauty
  • Atopic dermatitis reactions cause a variety of responses in the immune system, primarily causing hypertrophy of the immune system. Therefore, the spleen and lymph node weights were measured in order to observe the effect of the 5:
  • lymph node size The results for lymph node size are shown in Figs. 20 and 21, which alleviated the hypertrophy of both cLN (superficial cervical lymph node), aLN (axillary lymph node), bLN (brachial lymph node) and dLN .
